so, and more acuminate, beginning to taper immediately above 
the broad rounded base ; the anthodes considerably smaller ; the 
peduncles more erect, generally with less stellate down ; the phyl- 
laries rather narrower and less obtuse. 
From IT. corymbosum it differs in the leaves being thinner, 
less strongly toothed, rather less amplexicaul, more hairy, and not 
so numerous ; the anthodes smaller, much less numerous, and not 
in a large compound corymb, on longer and thicker and much more 
erect peduncles, with less stellate down and short black hairs ; the 
phyllaries rather more acute, with more numerous gland-tipped 
hairs, and in the florets not being quite glabrous at the tip when 
in bud ; but the ciliation of the ligules and the colour of the styles, 
I believe to be characters of very little importance. 
Straight-branched Uatckweed. 
Group D.— PRENANTHOIDEA. 
Stem leafy, without a basal rosette, corymbosely or paniculato- 
corymbosely branched at the apex. Lower leaves narrowed towards 
the base ; middle and upper ones amplexicaul with rounded auricles, 
glaucous and reticulate beneath, from the ultimate veins being 
apparent. Phyllaries few, imperfectly in 2 series ; those of the 
outer series very few, unequal ; all dark-olive, and thickly clothed 
with gland-tipped hairs ; the inner ones with pale margins ; none 
of them squarrose at the points. Achenes rather small, pale reddish- 
brown when ripe.

Stem very leafy, corymbosely or subpaniculato - corymbosely 
branched at the apex, sub-glabrous or sparingly hairy below, with 
black-based hairs above ; peduncles clothed with stellate down 
and very numerous gland-tipped hairs. Leaves distributed over 
the whole stem ; the lower ones oblanecolate, narrowed at the base 
or sub-petiolate with indistinct shortly-winged petioles ; inter- 
mediate ones elliptical-oblong sub-panduriform, amplexicaul with 
rounded auricles, acute ; uppermost ones lanceolate or ovate- 
hmceolatc, amplexicaul with rounded auricles, acuminate ; all sub- 
entire or denticulate in the middle, with the teeth remote and
